think big- As you said earlier, I feel very chassidisch, even if I don’t necessarily wear the begodim. All I can say is that, virtually always, I have found tremendous kavannah and indeed kedusha at mitzvah tenz. That, even when the one who danced BEFORE (not with) the kallah were family members. Somehow, it encapsulates the simcha and the reason for the wedding- to built a bays neeman. On a personal level, I have better kavonos during the mitzvah tenz than when the choosn kallah sit together and people dance before them-although this is the way of the gemoro. Whatever the reason, it always seems to me that during the mitzva tenz, the jetzer horah takes a break.
One quick note- why can’t you have no hefsek between chuppah and yichud? Unless, it is to be joitseh the rishonim that hold that the yichud is koneh. othwerwise, I don’t grasp the hefsek bit.
